Triangle PQR has vertex coordinates at P(4, 0), Q(6, 4), R(5, 1). If the triangle is translated so that Q′(9, 4), determine the translation direction and number of units.
3 units down
3 units up
3 units to the right
3 units to the left
It is translated 3 units to the right.
To find the translation direction and number of units, we can calculate the difference in x-coordinates between Q and Q′.
Q has coordinates (6, 4) and Q′ has coordinates (9, 4).
So, the translation is 9 - 6 = 3 units to the right.
